These hardy perennials are commonly known as Horsetail Rush or Scouring Rush. These plants grow wild in North America and are suited for planted at the edge of the water garden. Equisetum hyemale grows up to 4 feet high. It has hollow, bright green, furrowed stems that are banded with black; they resemble little Bamboo plants. Male plants produce a brownish pollen cone on their tips and female plants bear spikelet-like growths on their tips. Equisetum scorpoides, the Dwarf Horsetail, is a smaller plant with evergreen, twisted stems. It is even hardier than its taller cousin.

If these plants are not used to growing in water, they will need to be slowly adjusted by starting out with moist soil and gradually increasing the water. This plant is grown in the soil on the margin of ponds or streams. Plant them in 2-gallon containers in sun or partial shade. When transplanted, this plant will take a year or two before growth becomes vigorous again. Care must be taken as this plant can become invasive when planted near water. These plants stay green throughout the year, although old stems that die turn brown and dry. Prune them out to maintain a healthy appearance. Grow the Dwarf Horsetail with just a little water over it to avoid drowning it. It can be planted in small containers and set in sun or partial shade.

These plants can be increased by division.
